Do not lower malloc's to pass "sizeof" expressions like this:

ltmp_0_7 = malloc(((unsigned )(&(((signed char (*)[784])/*NULL*/0)[1u]))));
Instead, just emit the literal constant, like this:
ltmp_0_7 = malloc(784u);

Fix volatile load/store of pointers. Consider this testcase:
...
void %test(int** %P) {
%A = volatile load int** %P
ret void
}
void %test2(int*** %Q) {
%P = load int*** %Q
volatile store int** %P, int*** %Q
ret void
}
instead of emitting:
void test(int **l1_P) {
int *l2_A;
l2_A = (int **((volatile int **)l1_P));
return;
}
void test2(int ***l2_Q) {
int **l1_P;
l1_P = *l2_Q;
*((volatile int ***)l2_Q) = l1_P;
return;
}
... which is loading/storing volatile pointers, not through volatile pointers,
emit this (which is right):
void test(int **l1_P) {
int *l3_A;
l3_A = *((int * volatile*)l1_P);
return;
}
void test2(int ***l2_Q) {
int **l1_P;
l1_P = *l2_Q;
*((int ** volatile*)l2_Q) = l1_P;
return;

Also, optimize many function calls with pc-relative calls (partial prologue skipping for that case coming soon), try to fix the random jumps to strange places problem by pesimizing div et. al. register usage and fixing up GP before using, some calling convention tweaks, and make frame pointer unallocatable (not strickly necessary, but let's go for correctness first)
